Carbon nanotubes are considered as excellent reinforcements for improving the properties of ceramic composites. This paper reviews the reported techniques for the preparation of various ceramic coated CNTs, CNT-ceramic composites, CNT-ceramic composite coatings, etc. It is noted that a wide range of techniques have been used to fabricate these composites. Their characterisation has revealed that considerable improvements in electrical/thermal properties can be achieved, but only a few studies have demonstrated significant improvements in macro-scale mechanical properties of ceramics such as fracture toughness.
